Charged hadron multiplicities in e+ e- annihilations at s**(1/2) = 50-GeV - 61.4-GeV

The AMY collaboration Zheng, H.W. ; Perez, P. ; Auchincloss, Priscilla S. ; et al.
Phys.Rev.D 42 (1990) 737-747, 1990.
Inspire Record 295160 DOI 10.17182/hepdata.22922

We present the charged-particle multiplicity distributions for e+e− annihilation at center-of-mass energies from 50 to 61.4 GeV. The results are based on a data sample corresponding to a total integrated luminosity of 30 pb−1 obtained with the AMY detector at the KEK storage ring TRISTAN. The charged-particle multiplicity distributions deviate significantly from the modified Poisson and pair Poisson distributions, but follow Koba-Nielsen-Olesen scaling and are well reproduced by the LUND parton-shower model.

Fully corrected charged particle multiplicity distributions. Errors for n=2 and 4 are systematic only since these were derived using the LUND 6.3 Monte Carlo normalized to the observations at higher n values.

Charmed Multiplicities in $K^- p$ Interactions at 110-{GeV}/$c$

The Aachen-Berlin-CERN-Cracow-London-Vienna-Warsaw collaboration Ransone, G. ; Sixel, P. ; Kaufmann, H.H. ; et al.
Nucl.Phys.B 167 (1980) 285-291, 1980.
Inspire Record 144124 DOI 10.17182/hepdata.34553

The charged multiplicity distribution is presented for K − p interactions produced in the hydrogen bubble chamber, BEBC, using an r.f. separated, tagged K − beam of 110 GeV/ c momentum. A comparison with K + p, πp and pp data at lower energies shows that the main features of the multiplicity distributions depend on energy and charge of the incident particles, but not on their strangeness. At high energies, only the energy is important.

Multiplicities of Secondary Hadrons Produced in Neutrino $p$ and Anti-neutrino $p$ Charged Current Interactions

The Aachen-Birmingham-Bonn-CERN-London-Munich-Oxford collaboration Grassler, H. ; Lanske, D. ; Schulte, R. ; et al.
Nucl.Phys.B 223 (1983) 269-295, 1983.
Inspire Record 189061 DOI 10.17182/hepdata.33964

In an experiment with the hydrogen bubble chamber BEBC at CERN multiplicities of hadrons produced in νp and v p interactions have been investigated. Results are presented on the multiplicities of charged hadrons and neutral pions, forward and backward multiplicities of charged hadrons and correlations between forward and backward multiplicities. Comparisons are made with hadronic reactions and e + e − annihilation. In the framework of the quark-parton model the data imply similar charged multiplicities for the fragments of a u- and a d-quark, and a larger multiplicities for the fragments of a uu- than for a ud-diquark. The correlation data suggest independent fragmentation of the quark and diquark for hadronic masses above ∼ 7 GeV and local charge compensation within an event.

Inspire Record 203342 DOI 10.17182/hepdata.1999

Light ion collisions with carbon target at 4.2 GeV/c/N are studied. Pion multiplicity distributions, momentum and angular spectra are analysed. These data are described in terms of models assuming independent interactions of nucleons from the projectile nucleus with the target.

Charged Particle Multiplicity and Angular Distributions in Proton Emulsion Interactions at 800-{GeV}

The BATON ROUGE-CRACOW-MOSCOW-TASHKENT collaboration Abduzhamilov, A. ; Barbier, L. ; Chernova, L.P. ; et al.
Phys.Rev.D 35 (1987) 3537-3540, 1987.
Inspire Record 254225 DOI 10.17182/hepdata.3930

The interaction of 800-GeV protons in nuclear emulsion has been investigated. The multiplicities and angular distributions of charged particles emitted by both the projectile and the target nucleus have been measured for 1718 inelastic events and are compared with the data obtained in proton-emulsion collisions at 67, 200, and 400 GeV. The target excitation is found to be independent of energy while the production of secondary particles continues to increase with incident proton energy.

Production of Charged Hadrons, $\pi^0$ and Electron Pairs in 70-{GeV}/$c \pi^- p$ Interactions

The Bologna-Glasgow-Rutherford-Saclay-Turin collaboration Barloutaud, R. ; Baruzzi, V. ; Bird, I. ; et al.
Nucl.Phys.B 176 (1980) 285-302, 1980.
Inspire Record 153174 DOI 10.17182/hepdata.34414

Charged multiplicity and π 0 cross sections for π − p inelastic interactions at 70 GeV/ c are presented. The data were obtained from an exposure of the BEBC bubble chamber equipped with a track sensitive target (TST) to an unseparated negative beam at the CERN SPS. About 10 000 events were used for the charged multiplicity study, and about 2000 Dalitz pairs for the π 0 production analysis. A total of 12 e + e − pairs with a mass higher than the π 0 mass were found and analysed in terms of η or ω Dalitz pairs or decay pairs of vector mesons. Comparisons with data at other energies are made in terms of charged prong, π 0 cross sections, and of multiplicity parameters. The moments of longitudinal and transverse momentum distributions of the π 0 are determined and compared to the predictions of quark counting rule models.

Charged Particle Multiplicities in $B$ Meson Decay

The CLEO collaboration Alam, M.S. ; Csorna, S.E. ; Fridman, A. ; et al.
Phys.Rev.Lett. 49 (1982) 357, 1982.
Inspire Record 178492 DOI 10.17182/hepdata.20573

The charged multiplicity has been measured at the ϒ(4S) and a value of 5.75±0.1±0.2 has been obtained for the mean charged multiplicity in B-meson decay. Combining this result with the measurement of prompt leptons from B decay, the values 4.1±0.35±0.2 and 6.3±0.2±0.2 are found for the semileptonic and nonleptonic charged multiplicities, respectively. If b→c dominance is assumed for the weak decay of the B meson, then the semileptonic multiplicity is consistent with the recoil mass determined from the lepton momentum spectrum.
